About this role

NOTE:

• Send your resume to [email protected]

• Local to Atlanta, GA

• Hybrid is required

Short Description: Under general supervision, designs, codes, tests, modifies and debugs computer software.

Complete Description:

What This Role Actually Is

• DECAL's core licensing platform is a mission-critical application that supports childcare licensing, provider management, and program eligibility across the State of Georgia. We are in the middle of a major modernization effort, moving from a legacy ASP.NET architecture to .NET 8+, modern APIs, Azure cloud services, and a React-based user experience. This is not a maintenance or production support role.

• This position is for a senior engineer who wants to lead modernization efforts, solve complex technical problems and help shape the future architecture of a statewide platform. You will play a key role in technical design decisions, application architecture, cloud integration, and delivery.

• Our team is intentionally lean. That means ownership matters. You will be expected to take a solution from concept to production, including design, development, testing, deployment, documentation, and operational support. Success in this role requires initiative, accountability, and the ability to work independently.

• If you're looking for a highly structured environment where work is narrowly defined and tasks are handed to you step-by-step, this is probably not the right fit. If you enjoy building, leading, and owning outcomes, you'll thrive here.

Work Location:

• Must be physically located in Georgia

• Hybrid: Tuesday–Thursday on-site at DECAL headquarters, Atlanta (subject to manager

• discretion)

• Mandatory in-person: All Hands, Enterprise Applications meetings, DECAL All Staff, and

• designated on-site milestones

What You Will Do:

• Application Modernization (Core of this Role)

• Champion the modernization of DECAL's mission-critical licensing and eligibility applications, transitioning legacy solutions to modern .NET and Azure-based architectures.

• Design and implement scalable, secure, and maintainable application solutions that reduce technical debt and improve long-term supportability.

• Build and evolve API-first integrations and services that enable future platform capabilities.

• Develop cloud-native solutions using Azure App Services, Azure Functions, and related Azure

• Own the SQL Server platform, including data architecture, performance tuning, data migration, and platform modernization.

• Implement and maintain CI/CD pipelines using Azure DevOps to automate testing, deployment, and release management.

• Drive engineering excellence through code reviews, automation, documentation, and adherence to modern development practices.

Frontend & Integration:

• Build and maintain React-based UI components as part of the modernization roadmap

• Demonstrate a strong understanding of web application rendering patterns, including client side rendering (CSR), server-side rendering (SSR), component-based architectures, and modern frontend frameworks.

• Integrate third-party services and internal APIs; document every integration cleanly

• Implement and maintain reporting using SSRS and Power BI

• Participate in AI integration initiatives — Azure Agentic AI services, Copilot tooling, and chatbot integrations where applicable

Quality, Documentation & Support:

• Write code that your teammates can read and maintain six months from now

• Provide production support and own root-cause analysis when things break

• Maintain application documentation, deployment runbooks, and user-facing guides

• Participate in architecture reviews, code reviews, and sprint ceremonies

Required Qualifications:

EXPERIENCE

• 8+ years of professional .NET development experience — C#, ASP.NET MVC, Web API

• Demonstrated, hands-on experience migrating legacy ASP.NET applications to modern .NET (6, 7, 8 or 10) — not just exposure

• Production SQL Server experience: stored procedures, T-SQL tuning, schema migrations, data cleanup

• Azure hands-on: App Services, Function Apps, deployment pipelines, configuration management

• 5+ years delivering software in Agile (Scrum or Kanban) environments using ADO or GitHub

WHAT HANDS-ON MEANS HERE:

• You have modernized a real application — not a proof of concept — from legacy ASP.NET to .NET 6/7/8/10

• You have designed and maintained RESTful APIs that external systems depend on

• You have debugged production issues independently, without a team lead walking you through it

Preferred Qualifications:

• These will make you effective faster. They are not dealbreakers, but they distinguish competitive

• React experience — specifically building components within an existing application, not greenfield

• Exposer to .NET 10 Power BI or SSRS reporting development

• Experience with government, healthcare, or public-sector systems — you understand compliance, auditability, and data sensitivity

• Familiarity with ADA/WCAG 2.1 AA accessibility standards

• Exposure to Azure Agentic AI services or integration of AI-driven features in production applications

• Experience with middleware platforms such as Boomi or MuleSoft

• Background working with PII data and the security protocols that protect it

Education:

• Bachelor’s degree in computer science, Information Technology, or a related field — or equivalent work experience that demonstrates the same depth

What We Value Beyond the Technical:

• This team works on systems that affect real families in Georgia. We move fast because the mission

• requires it, but we do not cut corners on security, accessibility, or data integrity.

• Ownership: You finish what you start, and you tell people early when something is at risk

• Directness: You surface problems with a proposed fix, not just a flag

• Clarity under pressure: You can explain a technical constraint to a non-technical stakeholder

• without condescending or drowning them in jargon

• Adaptability: Government systems change scope. Requirements shift. You adjust without drama
